Application filed August 28, 1915. Serial No. 47,826,

To all whom it may concern:

Be it known that I, I-IERMANN H. SOHAR- MANN, a citizen of the UnitedStates, residing at Dunreith, in the county of Henry and State ofIndiana, have invented certain new and useful Improvements in AdjustableLand-Rollers for Drills; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

The invention relates to improvements in land rollers.

The object of the present invention is to improve the construction ofland rollers and to provide an adjustable land roller for drills adaptedto be readily mounted on the same and capable of being automaticallyadjusted with the cultivator beams of the drill to vary the width of thesame;

A further object of the invention is to provide a land roller of thischaracter which will also be capable of vertical adjustment to enablethe drill to penetratethe soil to the desired depth.

lVith these and other objects in View the invention consists in theconstruction and novel combination and arrangement of parts hereinafterfully described, illustrated in the accompanying drawings and pointedout in the claim hereto appended, it being understood that variouschanges in the form, proportion and minor details of construction may beresorted to without departing from the spirit or sacrificing any of theadvantages of the invention.

In the drawing Figure 1 is an end elevation of a land roller constructedin accordance with this invention and shown applied to a portion of adrill, Fig. 2 is a vertical sectionalviewtaken longitudinally of theland roller, Fig. 3 is a plan view of one end of the land roller.

Like numerals of reference designate corresponding parts in the severalfigures of, the drawing.

In the accompanying drawing in which is illustrated the preferredembodiment of the invention the land roller 1 comprises in itsconstruction two relatively adjustable telewhich may partially close theouter ends of the sections or entirely close the same as desired and thesaid heads are provided with curved outwardly extending flanges 5 whichare suitably secured to the tubular sections 2 and 3. The heads areequipped at their centers with suitable outwardly projecting pivots 6which are arranged in bearings 7 of vertical standards 8 which havetheir lower portions bent inwardly at 9 to arrange the bearings withinthe outer ends of the tubular sections 2 and 8. The pivots may besecured to the head 4 in any desired manner and they are preferablyretained in the bearings of the vertical standards by pins or keys 10but any other suitable locking means may of course be employed for thispurpose.

The standards are mounted in openings or eyes 11 of attaching bars ormembers 12 which are secured to the adjustable beams 13 of the drill bybolts ltor other suitable fastening devices. The standards 8 preferablyconsist of round rods and the attaching bars are provided at theeyes 11with set screws 15 which are tightened after the parts have beenadjusted. The round standards and the eyes or openings 11 together withthe telescopic sections 2 and 3 of the roller enable the beams 13 whichdiverge rearwardly in the usual manner to be adjusted toward and fromeach other. The set screws 15 also secure the standards in theirvertical adjustment and arrange the land roller in proper relation withthe soil engaging devices 16 of: the drill so that the soil engagingdevices'may penetrate the soil to'the desired depth. 7

What is claimed is':.
